查询词典 Dam

The rotation of principal stress axes for certain elements in dam are examined.

建议进行恒p、恒q或η=q/p为常数的加载路径试验，这对于合理预测堆石坝在应力路径转折等复杂应力路径下的性状是有利的。

By using Duncan-Chang E-B model, the grouting period-stopping period of a earth rock dam, and the finite element analysis of stress and strain. Split-grouting can increase the maximum and minor principal stresses at the same time.

采用Duncan-Chang非线性模型，模拟了某土石坝劈裂灌浆的灌浆－停灌施工过程，进行了应力、应变、稳定有限元分析。

In the neighborhood area of grouting axes, the minor principal stress increased more extent than the maximum one. The stress level was reduced and lower than before; and the stability of the earth dam increased.

劈裂灌浆可以同时增大大小主应力，在灌浆轴线附近区域，小主应力增加幅度大于大主应力增加幅度，应力水平较灌浆前降低，土坝稳定性增加。

The minor principal stress of slab, the maximum acceleration in up-down stream direction and permanent deformation of the dam body for three-directional earthquake excitation are obviously different from those for unidirectional and two-directional earthquake loading.

计算表明，多向地震动下的面板峰值小主应力、顺河向峰值加速度及坝体的永久变形均与单向和双向输入时显著不同，实际工程计算时应同时考虑三个方向的地震动；振动型地震激励引起的坝体反应明显大于冲击型地震激励；随着地震动强度的增加，峰值加速度、峰值剪应变、面板应力和周边缝变形等增加；面板刚度对面板的应力值和周边缝的变位具有较大影响，当面板模量取值较低时，计算所得到的"面板"应力集中部位不甚明显，计算结论为新型的"土工膜面板堆石坝"提供了理论依据。

At last, this paper analyses the probability of dam's seepage and demonstrates the capacity of the project on this site.

确定了可建场的主坝及拦污坝的持力层，分析了该场地产生渗漏的可能性，论证了该场址的适宜性。

A novel optoelectronic detecting method based on projective geometry is proposed to monitor the horizontal and vertical displacement of measured points of a structure such as dam and huge straight building.

为了同时对大坝等大型建筑物被测点水平和垂直方向的移位进行监测，提出一种基于几何投影关系的光电检测方法。

Are the main materials of the anti -leakage body for the works of urban landfill waste site and refuse dam .

人工衬里(土工织物及HDPE膜等)是城市生活垃圾卫生填埋场场区及垃圾坝工程防渗体的主要材料。

To establish the condition index curve regular, it can assess dam condition with different time, according to the result of condition index curve.

最后将所获得的渗水量数据，取其非丰水期、且水库水位和渗水量的相关系数大於0.85以上值，做为筛选出不受降雨影响的渗水量值。

Survey on the overall underground tunnels, survey on the ground and surface and tailings dam relief map

对所有坑道进行测量，对尾矿坝地形图进行测量。

Try to dam its movement at one point, and slowly but remorselessly it will find its way around.

试图在某一点位堵住资本的移动或者阻碍它的流速，结果它终将毫不犹豫地找到自己的解决的方式。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
